Phytic Acid & The Paleo Diet
There are many benefits to adhering to the Paleo diet as a means of getting rid of body fat and helping to reduce the likelihood of a number of illnesses. One of the benefits of the Paleo diet is that it can help to reduce phytic acid intake. It obliterates foods which are full of phytic acid in favour of those which contain low levels such as fruits and vegetables.
Phytic acid is highly obstructive as it has the ability to stop essential minerals from being absorbed. These minerals include magnesium, iron and calcium, which are important as part of any healthy diet. Phytic acid binds itself to these minerals and as our bodies can’t break them down, it can result in a number of health issues. There are many people who consume high levels of cereal, as they believe that this is beneficial to the health but in fact these are one of the main culprits of phytic acid. As a result, they can actually prove to be quite damaging to the health. As our ancestors substituted cereals for other healthy foods such as vegetables and fruits, it was a much healthier way of living which is why the Paleo diet is the best one to follow.
The health issues which can result from a diet which is high in phytic acid include PMS, stomach cramps and skin problems, which can be very detrimental for our quality of life. There are many people who also suffer from anaemia, which is caused by iron deficiency and it is believed that this could be caused through a high phytic acid diet. The Paleo diet promotes an eating plan which minimises the intake of foods which contain phytic acid, in order to promote a healthier lifestyle.
The right diet is the most important way of maintaining good health and more often than not, most of us will reach for the painkillers when we feel unwell, rather than getting to the root cause of the problem. There are certain foods which are extremely high in phytic acid and these are best to completely stay clear of when following the Paleo diet. The most common of these are grains and legumes. These foods can be replaced with fruits, vegetables and nuts and seeds, which are full of minerals and antioxidants.
Nuts and seeds are quite high offenders when it comes to levels of phytic acid but you can minimise these by soaking them in purified water. Nuts are full of health benefits, but should only be eaten in moderation; otherwise they will be counter productive. As far back as our ancestors, people were soaking their nuts and seeds and as the reason behind the Paleo diet is to go back to our roots, it is a ritual we should bear in mind when trying to reduce our intake of phytic acid. The best way to achieve this is to soak the nuts in purified water, cover them and add sea salt. You should then give them a rinse and drain them, before putting them in the oven at the lowest possible temperature. It may seem like a bit of a lengthy process, but the benefits to help are worth taking these steps.
In order to really get the balance between the right nutrients and lowering levels of phytic acid, it is worth educating ourselves on the content of our foods so we are more aware of whether or not they will be detrimental to our health. There are plenty of nutritious foods to eat as part of the Paleo diet, which will result in noticeable changes to your health and fitness levels. Good combinations of the right foods, together with an exercise plan will not only improve your appearance, but will also help you to enjoy a longer and more fulfilling lifestyle.
If you find any of the foods on the Paleo diet are bland, you can always season them with apple cider vinegar as this is a tasty substitute to high calorie mayonnaise and it offers lots of health benefits. It can take a while to get used to following the diet, but it can be really beneficial to the body and appearance. It will soon become a way of life and reducing phytic acid levels is just one of the many benefits of following this simple but effective diet.
How Phytic Acid Affects Nutrient Absorption
Phytic acid, also known as phytate when in salt form, is often found in the outer layer of seeds, nuts, legumes, and grains. While it serves a protective function in plants, its impact on human health is more complex. Once ingested, phytic acid binds to positively charged minerals like zinc, calcium, magnesium, and iron — forming insoluble complexes that the body cannot absorb. This effectively reduces the bioavailability of these essential minerals, even when your diet includes an otherwise adequate intake.
Over time, consistent consumption of foods high in phytic acid can contribute to deficiencies, particularly for individuals who are already at risk of low mineral levels. This is especially concerning for women (due to menstrual blood loss and pregnancy), children, athletes, and those recovering from illness. The Paleo diet naturally avoids high-phytate foods by steering clear of legumes and grains, making it a practical approach to maintaining mineral balance without the need for supplementation.
Modern Misconceptions About ‘Health Foods’
Marketing has led many people to believe that breakfast cereals, wholegrain bread, and granola bars are healthy daily staples. Yet, these products often contain high levels of phytic acid due to the processing of wheat, oats, soy, or other legumes. While fortified with synthetic vitamins and minerals, the phytic acid content can still impair absorption, particularly in the case of non-heme iron — the type found in plant foods.
When viewed through a Paleo lens, these so-called health foods lose their appeal. By focusing on bioavailable nutrients from natural sources — such as leafy greens, animal proteins, and fermented or properly prepared nuts — the Paleo diet offers a far more effective way to nourish the body without interfering with digestion or mineral uptake.
Traditional Practices for Reducing Phytic Acid
Long before modern science understood the implications of phytic acid, traditional cultures developed food preparation techniques that naturally reduced its levels. Soaking, sprouting, fermenting, and slow-cooking were commonplace, especially for legumes and grains. These methods activate phytase, an enzyme that breaks down phytate and helps release the bound minerals.
While Paleo largely avoids grains and legumes, nuts and seeds are still included — though in moderation. Applying the same ancestral wisdom of soaking and low-temperature dehydrating allows you to enjoy these foods without the same anti-nutrient load. If you regularly consume almonds, walnuts, sunflower seeds or pumpkin seeds, it’s worth adopting a soaking routine as part of your food prep rituals.
Meal Planning for Low Phytic Acid Living
Creating balanced Paleo meals that avoid phytic acid and support optimal nutrition is easier than it sounds. Here are some simple ideas:
- Breakfast: Scrambled eggs with sautéed kale and mushrooms, plus half an avocado
- Lunch: Grilled chicken breast over a salad of rocket, cucumber, beetroot, and olive oil dressing
- Dinner: Baked salmon with roasted sweet potato and steamed broccoli
- Snack: A small handful of soaked and dehydrated cashews or macadamias
These meals are rich in micronutrients, contain minimal to no phytic acid, and offer plenty of fibre and healthy fats — all essential for sustained energy and long-term wellness.
The Long-Term Benefits of Reducing Phytic Acid
In addition to improving nutrient absorption, reducing dietary phytic acid can lead to noticeable improvements in energy, mood, skin clarity, and digestion. Many people who switch to Paleo report a reduction in bloating, fatigue, and cravings, especially when high-phytate foods are eliminated. Over time, the cumulative benefits of improved mineral status can lead to stronger immunity, better hormonal balance, and increased bone density.
Furthermore, minimising anti-nutrients like phytates can be particularly important for those with gut conditions such as IBS, SIBO, or leaky gut syndrome. By removing dietary irritants, the gut lining has a chance to heal and absorb nutrients more effectively — often leading to fewer symptoms and better overall resilience.
Final Thoughts on Phytic Acid and the Paleo Diet
Reducing phytic acid is just one of many advantages to living Paleo. By emphasising whole, nutrient-dense foods that don’t compete with your body’s ability to absorb essential minerals, you’re building a strong foundation for lifelong health. It’s not about restriction — it’s about making food choices that align with how our bodies evolved to thrive.
If you’re just beginning your Paleo journey, don’t stress about perfection. Focus first on removing the obvious offenders — cereals, bread, legumes — and get comfortable with preparing whole meals from scratch. Over time, you can add in practices like soaking nuts and rotating seasonal produce for even better results.
